A new ransomware is being distributed by the Magnitude exploit kit: Magniber (detected by Trend Micro as RANSOM_MAGNIBER.A and TROJ.Win32.TRX.XXPE002FF019), which we found targeting South Korea via malvertisements on attacker-owned domains/sites. The development in Magnitude’s activity is notable not only because it eschewed Cerber—its usual ransomware paylo

BlueBorne is a set of vulnerabilities affecting the implementation of Bluetooth in iOS, Android, Linux, Windows and Mac OS* devices. According to the researchers who uncovered them, BlueBorne affects around 5.3 billion Bluetooth-enabled devices. The immediate mitigation for BlueBorne is to patch the device, if there’s

The company ZERODIUM announced it will pay up to $1 million for fully working zero day exploits for Tor Browser on Tails Linux and Windows OSs.
The zero-day broker Zerodium offers $1 million for Tor Browser exploits with the intent to unmask Tor users. The controversial firm will then resell the zero-day exploit for Tor browser to law enforcement and governm

Fileless malware can be a difficult threat to analyze and detect. It shouldn’t be a surprise that an increasing number of new malware threats are fileless, as threat actors use this technique to make both detection and forensic investigation more difficult. We recently found a new cryptocurrency miner (which we detect as TROJ64_COINMINER.QO)

The exploit kit landscape has been rocky since 2016, and we’ve observed several of the major players—Angler, Nuclear, Neutrino, Sundown—take a dip in operations or go private. New kits have popped up sporadically since then, sometimes revamped from old sources, but none have really gained traction. Despite that fact,

In many instances, researchers and engineers have found ways to hack into modern, internet-capable cars, as has been documented and reported several times. One famous example is the Chrysler Jeep hack that researchers Charlie Miller and Chris Valasek discovered. This hack and those that have come before it have mostly been reliant on specific vulnerabilities

Cybercriminals targeting gamers are nothing new. We’ve reported many similar incidents in the past, from fake game apps to real-money laundering through online game currencies. Usually the aim is simple: to steal personal information and monetize it. And usually, for that purpose the game itself is abused.
In the particular scenario we are describing in this

A malicious email campaign against Russian-speaking enterprises is employing a combination of exploits and Windows components to deliver a new backdoor that allows attackers to take over the affected system. The attack abuses various legitimate Windows components to run unauthorized scripts;

We’ve uncovered a new exploit kit in the wild through a malvertising campaign we’ve dubbed “ProMediads”. We call this new exploit kit Sundown-Pirate, as it’s indeed a bootleg of its precursors and actually named so by its back panel.
ProMediads has been active as early as 2016, employing Rig and Sundown exp

A seven-year old vulnerability in Samba—an open-source implementation of the SMB protocol used by Windows for file and printer sharing—was patched last May but continues to be exploited. According to a security advisory released by the company, the vulnerability allows a malicious actor to upload a shared library to

Last month’s Patch Tuesday highlighted updates for older Windows versions to address vulnerabilities responsible for the WannaCry outbreak. This month’s Patch Tuesday shifts its focus to other technologies, with an update that addresses 54 vulnerabilities – including one in the augmented reality sphere.
One notable vulnerability in this month’s Patch T

Last month, in reaction to the WannaCry outbreak that affected Windows users all over the world, Microsoft released a patch for Windows XP—an operating system it had stopped supporting in 2014. As part of the June Patch Tuesday cycle, Microsoft has decided to issue patches for XP and other older platforms that have reached End of Support (EOS) status. They c

Imagine a well-experienced security analyst at a major company going through his normal routine of checking logs at the end of the workday. A quick look at the company’s security solution logs reveal nothing too peculiar or alarming — except for one thing: a higher than normal amount of traffic to the office’s newly introduced third-party chat platform.

The EternalBlue exploit took the spotlight last May as it became the tie that bound the spate of malware attacks these past few weeks—the pervasive WannaCry, the fileless ransomware UIWIX, the Server Message Block (SMB) worm EternalRocks, and the cryptocurrency mining malware Adylkuzz.
EternalBlue (patched by Microsoft via MS17-010) is a security flaw relate
